A foldable automobile headrest frame structure comprises a connecting rod and a connecting frame, the connecting frame is rotatably connected with a cross rod at the bottom of the connecting rod, a locking mechanism and a connecting rod reset mechanism are arranged on the connecting frame, and the locking mechanism comprises a rotating wheel, a turning wheel, a locking block, a locking block reset mechanism and a buckle block. The buckle block is fixed to the cross rod, the locking block is connected into the connecting frame, the locking block abuts against the buckle block, the locking block is connected with the first pull rope, the first pull rope is connected with the rotating wheel through turning of the turning wheel, the rotating wheel is connected into the connecting frame, the second pull rope is wound around the rotating wheel, the second pull rope is fixed to the rotating wheel, and the second pull rope penetrates through the connecting frame. The distance from the joint of the first pull rope and the rotating wheel to the rotating center of the rotating wheel is smaller than the distance from the joint of the second pull rope and the rotating wheel to the rotating center of the rotating wheel. The foldable automobile headrest frame structure has the advantages that the space occupied by the locking mechanism in the connecting frame is small, and unlocking is labor-saving.
